The twelve major keys are arranged clockwise in steps of a fifth, starting with C at the top. Each step to the right adds one sharp to the key signature; each step to the left adds one flat. The inner ring holds each key's relative minor, the minor key that shares the same notes. C major and A minor sit together because neither has any sharps or flats.
The six chords that belong together
Pick any key and the keys on either side of it give you its other two main chords. In C, that is F and G, the IV and V, with the relative minors Dm, Am and Em beneath. Those six chords cover most of popular music. Read the same six chords from the minor ring and their Roman numerals change, which is the difference between A minor and C major.
